Sure. Install and operate your own mail server. Be prepared to pay for a
static IP address if you don't want to get blacklisted while using a dynamic
IP address, and learn how to secure your mail server, and pay for anti-spam
programs that work with your choice of e-mail server, and ...

Do it yourself to have control. Use someone else's property and you get
what they give you.

E-mail is NOT a reliable file transfer mechanism. It wasn't intended or
designed for that. It was designed to send lots of small messages. There
is no CRC check on the file to ensure integrity. There is no resume to
re-retrieve the file if the e-mail download fails. There is no guarantee
the e-mail will arrive uncorrupted. Large e-mails can generate timeouts and
retries due to the delay when anti-virus programs interrogate their content.

Do not use e-mail to send large files. It is rude to the recipient. Not
every recipient might want your large file. Not every recipient has
high-speed broadband Internet access. Many users still use slow dial-up
access, especially if all they do is e-mail. You waste your e-mail
provider's disk space and their bandwidth to send a huge e-mail. You waste
the e-mail provider's disk space and bandwidth at the recipient's end. You
eat up the disk quota for the recipient's mailbox (which could render it
unusable so further e-mails get rejected due to a full mailbox). You
irritate users still on dial-up that have to wait eons waiting to download
your huge e-mail. Some users have usage quotas (i.e., so many bytes/month)
and you waste it with a file that they may not want. Don't be insensitive
to recipients of your e-mails. Take the large file out of the e-mail.

Save the file in online storage and send the recipient a URL link to the
file. Your e-mail remains small. It is more likely to arrive. It is more
likely to be seen. The recipient can decide whether or not and when to
download your large file. Be polite by sending small e-mails.

Your ISP probably allows many gigabytes of online storage for personal web
pages. Upload your file there and provide a URL link to it. Other methods
(of using online storage), all free, a

If it is sensitive content and when storing it online in a public storage
area or to guard it against whomever operates the online storage service,
remember to encrypt it.
